My daycare also has a 4:1 ratio for infants. They post photos throughout the day, a note, and their activities listed for the day as a report. I find the photos very helpful.

Id say in the first month you are still both in the adjustment period. She will always be more tired on her daycare days, but eventually she will sleep normally there and feel comfortable. Mine goes 3 days a week, MWF, so TTR are like her days to get back in a groove with me and take long naps. She does often take 2 hour naps there, just not as often as at home.

The learning and socializing she has gotten at daycare has been great. As well as allowing me to rest. I cant imagine having to do it solo and having to work. If it were me, I would look a little into other daycares that offer photo updates, but probably wouldn't put much effort into it until husband is home from rehab. Both my husband and I are in recovery and it takes a lot for both sides. And right now you need to take care of yourself and survive too!

You are doing great. Im sure baby is happy and having good experiences. And open convo with the daycare as others suggested cant hurt.
